Comment(by danielk):

 (In [14009]) Refs #3680. Avoids segfault on failed video resolution

 Darek's video contained some errors that made MythTV think the resolution
 had suddenly changed to 1328x3536. VideoOutputXv failed to allocate a
 buffer of this size for XVideo. This change makes sure that VideoOutputXv
 enters the error state which propagates to both NuppelVideoPlayer and
 AvFormatDecoder so that decoding can be shut down before we try to use
 non-existant buffers in AvFormatDecoder::GetFrame() after the error.
